If a function calls itself (a recursive function), or if a chain of function calls becomes too long, the call stack can overflow. When a function completes, its entry is removed from the top of the call stack.

Each time a function is called, a new entry is added to the top of the call stack. The call stack is a data structure used by JavaScript to keep track of function calls.

If we set the recurring timer in our code the reference to the object from the timer's callback will stay active for as long as the callback is invocable.Ī "stack overflow" occurs in JavaScript when the call stack exceeds its maximum size.

Forgotten timers or callbacks: Having a setTimeout or a setInterval referencing some object in the callback is the most common way of preventing the object from being garbage collected.

To avoid this, make sure to release any references to large data structures when they are no longer needed.

Large data structures: Large data structures, such as arrays or objects, can consume a lot of memory if they are not properly managed.

To avoid this, avoid creating unnecessary closures and make sure to release closures when they are no longer needed. When a function creates a closure, any variables in the outer function that are used in the inner function will remain in memory until the closure is released.

Closures: Closures are a powerful feature of JavaScript, but they can also cause memory leaks.

To avoid this, always remove event listeners when they are no longer needed. If an element with an attached event listener is removed from the DOM, but the listener is not removed, it can cause a memory leak.

Forgotten event listeners: When an event listener is attached to an element, the listener function remains in memory until it is explicitly removed.

Here are some common causes of memory leaks in JavaScript and how to avoid them: Memory LeakĪ memory leak occurs in JavaScript when the program continues to allocate memory without releasing it, leading to a reduction in the available memory of the system, which may eventually lead to the program crashing. Given that we have limited access to these resources, it is crucial to write efficient code that can prevent issues like stack overflow or memory leaks, and to effectively manage memory usage. It is important to keep in mind that memory is a finite resource, and in JavaScript, memory is stored in two places: the call stack and the memory heap.
